COMBINED BUMPER AND JACK Filed Aug. 19, 1936 2 Sheets-Sheet 2 ATTORN EY6Patented Apr. 13, 1937 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to combined bumper and jacks for motor vehiclesand has for an object to provide a bumper and a lifting jack in aunitary assembly adapted to be associated with the vehicle frame to beused horizontally as a bumper and adapted to be rocked to the verticalon either side of the frame for use as a jack.

With the above and other objects in view the invention consists ofcertain novel details of construction and combinations of partshereinafter fully described and claimed, it being understood thatvarious modifications may be resorted to within the scope of theappended claims without departing from the spirit or sacrificing any ofthe advantages of the invention.

In the accompanying drawings forming part of this specification,

Figure 1 is a front elevation of a combined bumper and jack constructedin accordance with 'the invention and shown in applied position.

Figure 2 is a plan view of the parts shown in Figure l.

Figure 3 is a View similar to Figure 1 but showing the device inposition for use as a jack.

Figure 4 is a detail sectional view showing the bolt for rigidly andpivotally mounting the bumper and jack on the vehicle frame.

Figure 5 is a cross sectional view taken on the line 5--5 of Figure 4. f

Figure 6 is a detail longitudinal sectional view of the means foractuating the jack.

Referring now to the drawings in which like characters of referencedesignate similar parts in the various views, lll designates the frontends of the longitudinal sills or frame bars of a motor vehicle l I,these bars being provided at the front ends with screw threaded openingsl2 for mounting the combined bumper and jack corn-I prising the subjectmatter of the invention.

The bumper i3 is in the nature of a flat bar having the ends I4 curvedrearwardly, the bar being provided intermediate the ends with openingsl5, one of which is shown in Figure 5, to receive sleeves I6 througheach of which a bolt Il is passed, the same having a wrench head I8 onone end and having the other end screw threaded as shown at i9 forengagement in the associated threaded opening I2 in one of the framebars, for attaching the bumper to the vehicle in horizontal position asbest shown in Figure 1.

The jackl@ is in the form of a rod of substantially the same length asthe bumper and having the ends equipped with flared feet 2l adapted torest upon the ground when the jack is in use to elevate either one ofthe front wheels, or rear wheels as will presently be described. flhejack slidably fits in openings 22 formed in blocks 23 which are providedwith respective openings 24 to snugly receive the above mentioned sleeveI6. The sleeve is provided with a collar 25 on the inner end which bearsagainst the block and is also provided with a` collar 26 on the outerend which bears against the bumper I3, as shown in Figures 4 and 5.

A helical spring 2l is confined under compression on the sleeve betweenthe block and the bumper and tends constantly to spread the bumper andthe block apart to prevent rattling. An arcuate leaf spring 28 issecured to each block and bears with its free end against the inner faceof the bumper and also tends constantly to hold the block and the bumperspread apart to prevent rattling.

The jack is provided centrally with a screw thread 29 which meshes withan internally threaded bevel gear 30 carried by the bearing 3| on anL-shaped bracket 32 which is bolted, riveted, or otherwise secured tothe bumper as shown at 33 and which is provided with a bearing 34 whichreceives a shaft 35. The shaft is equipped at the inner end with a bevelgear 36 which meshes with the bevel gear 30 and is equipped at the outerend-with wrench faces 31. The shaft passes loosely through an opening 38in the bumper |3`and is equipped with a collar 39 which bears upon theouter face of the bumper and holds the shaft and bevel gear assembled inthe bearing 34.

In operation, either of the bolts I1 may be backed out by applyingthereto the same wrench lil that is used to loosen the rim bolts of thewheels. 'Thereupon the unitary assembly of bumper and jack may be rockedupon the other bolt l1 as a pivot to the position shown in Figure 3. Thewrench 4E) may now be applied tothe wrench faces 3l of the shaft 35 androtated in a direction to feed the jack 29 through the bevel gear 3i)and elevate the wheels of the Vehicle to permit removal thereof in thecustomary manner. After repairs to the wheel have been madel the wrenchmay be rotated in the opposite direction to feed the jack upwardlythrough the bevel gear 30 and lower the wheel to the ground in the usualmanner. 'I'he bumper and jack may be now rocked to the horizontalposition and secured in place by advancing the first mentioned screw l1into the corresponding threaded opening I2 in the frame bar.

From the above description it is thought that the construction andoperation of the invention will be fully understood without furtherexplanation.

What is claimed is:

1. In combination, a motor vehicle bumper, a

5 lifting jack extending longitudinally of the bumper, means for rigidlyand pivotally mounting the bumper and jack upon a Vehicle frame, saidjack being in the nature of a rod having terminal feet, a bracket on thebumper, mesh- 10 ing bevel gears carried by the bracket, one of thegears having a screw thread connection with the jack, a shaft for theother gear terminating in wrench faces, and anti-rattling means betweenthe bumper and the jack.

15 2. A combined bumper and jack comprising a flat bar, there beingspaced openings in the bar, sleeves in the openings, bolts in thesleeves having wrench heads, said bolts being adapted to be threadedinto openings formed for the reception thereof in a vehicle frame, ajack in the form of a rod of substantially the same length as the bumperand having the ends equipped with feet adapted to rest upon the ground,blocks snugly receiving said sleeves and receiving the jacks for slidingmovement endwise with respect to the bumper, and gear operated feedscrew means for sliding the jack to operative or to released position.

3. A combined bumper and jack comprising a bar, sleevescarried by thebar, attaching bolts in the sleeves, said bolts being adapted toindividually form a pivot on which the bumper may be swung in a verticalplane, a jack, blocks carried by said sleeves and slidably receiving thebumper, antierattling springs between the blocks and the bumper, andgear operated feed screw means for moving the jack lengthwise of thebar.
